Skills Checklist — Communication Milestones Ages 0–5
Is my child on track?
This checklist was designed for the parent who has quietly wondered whether their child is hitting the right milestones — but didn't know where to look or who to ask.
Organized by age from birth through 5 years, this guide walks you through the communication skills that a typical child is developing at each stage — from early sounds and gestures to vocabulary, sentence structure, and school-readiness language skills.
Inside this guide:
Age-by-age communication milestones from 0–5 years
Skills across listening, understanding, speaking, and speech sounds
A note on what to do if something doesn't feel right
This guide is for you if:
Your child is approaching a new age milestone and you want to know what to expect
Someone mentioned a concern and you want to understand what typical development looks like
You just want peace of mind — or a reason to seek a professional for guidance
Created by Sarah Chu, M.S. CCC-SLP — a bilingual, licensed speech-language pathologist specializing in early language development.
